Cyclists are a road user same as cars, motocyclists, pedestrians etc. The public road system is for all road users. Respect the fact that your fellow human being is unprotected and give them the same/more respect as any other road user. As a regular cyclist, I see the unsolicited angst against cyclists all the time. There is no need for hero car drivers to brush past you with 3" clearance, blast the horn, rev limit your diesel and haze us in black smoke. So understandably we get upset as you are potentially trying TO KILL US !!
You might be just f**king around but it is the cyclist that will be in hospital or dead. Think about that a little.
Dont ever try this shit on me as if you happen to get caught at a red light...I'm dragging you out of your car and beating the @#$% out of you as a lesson.(about once a month on average and the heroes are invariably spineless cowards that whimper alot)
So chill and show the cyclists some respect, it may just be someone you know.
